[LarrysDrifter]

Go to youtube and type in FruitysBoats.Im not sure if its his Maritimo,but it flies!Id link it,but I dont know how.

Guys,
it's not my maritimo, the Maritiomo was a bit slower than this one, it is a cat called a MasoKat from Fast Electrics in Australia, power is 2 x 1515 1Ys (2200kv) on 5S, so that't approx 40,700 rpm at 18.5 volts, a few more at full charge!

Speed is 122kph, we do intend to hook 6S up to this cat one day, it will either blow up, or absolutally fly.

The vid was the first ever run too, no tuning etc...

thats like comparing apples to oranges though, lol

maybe big apples and small apples, lol

Feigao 580L : 45mm diameter 76 mm length, 545 grams
Leopard 4074: 40mm diameter, 74 mm length, 375 grams

Leopard is smaller, lighter and MORE powerful

I did some testing in my H&M Intruder with a Leopard 4074 and a Feigao 8XL, both running 5S. I know it's not a direct equivalent, but speed wise they were identical, the only difference was the temperature. Feigao was too hot to touch (did not have my temp gauge) and the Leopard was completely cold...

Because I cooked a Feigao 10XL in my Titan 29" I ordered and got a Leopard 4074 2000Kv two days ago.
My setup is 5S2P Zippy 5000mAh 40C and Seaking 120A ESC.
The 10XL overheated at 86°C=186F after 5 minutes at full trhottle with an X440 prop and the speed was only 58Km/h = 36Mph.
The problem could be the boat was running too wet, the COG was @ 34% from the transom.
Now I have moved the batteries more back and I will try a COG @ 30% with the Leopard 4074.
My Leopard came with 4mm bullets, are them too small to handle 1500W continuous?
What bullets are you using with Leopard 4074?

[CornelP]

I standardized on 5.5mm, I just feel better. Normally the factory 4mm could be ok, but it's easy and cheap enough to go one size bigger. Plus most of my packs came with the 5.5mm bullets...

something was most definatley wrong for that motor to get that hot that fast on 5s!

i'm running the 10xl on 6s 5000mah 30c x442, 60mph, 130f after full length run.

Fruity,that video was the 1st FE boat Ive seen run and was my inspiration to get into boats.I still watch it sometimes just to hear the sound of the props.Thank you for posting the video.
And for my wallet being empty from getting addicted to FE.

just got my ul-1 and would like to use this setup the leopard4074 2200kv/turnigy120a esc/turnigy5000mah 2s 1p 40c with 5.5 bullet
my worries are heat and would it work

[Fluid]

It won't work on 2S1P, you need 4S1P. The motor will work with the right prop, start with an m440 and work up. Check heat often the first few times, but if the boat runs freely you should be okay.
